Exponential Functions and Properties

The video tutorial explains how to calculate the average rate of change for an exponential function over a given interval. It involves plugging in the interval's bounds into the function to find the corresponding Y values and then determining the difference between these Y values. The process is broken down into steps, including calculating the lower and upper bounds and finding the difference between the results.
